Curcumin, Turmeric and Cancer
Many people take turmeric or curcuminoids for their anti-inflammatory and/or anticancer properties. But how accurate are the labels?
Consumerlabs.com recently evaluated 10 popular turmeric and curcumin supplements. They found that two of them were underpowered. “Advance Physician Formulas” claimed that their supplement contain 245 mg of curcumin. But they only contain 18.9 mg! Similarly, Paradise Herbs and Essential Turmeric is said to contain 125 mg of curcuminoids per capsule. But it only contains 18.4 mg (or 14.7 percent of the stated amount).
The good news was that all the other brands delivered what they promised. This includes such well known brands as Solgar, Swanson, Jarrow and GNC. Life Extension Super Curcumin with Bioperene was also as advertised. It is a good bargain as well, 17 cents per 500 mg of curcuminoids. It contains BioPerine, which aids adsorption.
